In order to solve the problem of high sintering temperature and reduce the machining costs, the W/ZrC composites were successfully fabricated by the reactive melt penetration (RMP) of Zr2Cu alloy into the porous W/WC presinters at 1400 ℃ for 2 h. Comparing with the conventional powder metallurgy (PM), this process can reduce the fabrication temperature for about 500 ℃. The W/ZrC composites fabricated by this process have homogeneous microstructure and higher relative density with the maximal flexural strength and elastic modulus of 600 MPa and 360 GPa, respectively, and the maximal fracture toughness of 11 MPa·m1/2, four times higher than that of pure ZrC.
